Nitrogen(N) concentrations of human milk in various fractions, such as total, protein, nonprotein, whey protein and casein were determined at 2-3 days, 1, 2, 4, 6 and 12 weeks of postpartum. significant decreases in total N, nonprotein N, protein N, whey protein N and casein N were found with time postpartum. Total nitrogen decreased from 401mg/dl at 2-3 days to 211mg/dl at 12 week. Whey protein nitrogen was found to contribute to the total nitrogen decrease with time. The percentage of nonprotein nitrogen was 13% in colostrum and 17-18% in mature milk. The proportions of whey protein and casein nitrogen were 55:45 at 2-3 days and 34:66 at 12 week postpartum. These determinations will provide the basic information on the variability of nitrogen components as lactation proceed.

The possibility of the use of soy sauce koji and commercial proteolytic enzyme for the acceleration of fish fermentation without affecting its characteristic flavor and nutritional quality inherent to the final products was investigated. Fish sauces were prepared experimentally from small horse mackerel under sixteen kinds of conditions and the chemical composition of those were examined, individually. The amino type nitrogen content, ration of amino type nitrogen to total nitrogen and protein conversion ratio were the highest in the fish sauce product treated with soy sauce koji, of which 10% salt was added to the minced raw fish at the start and additional 10% salt was added to the mixture after 48hrs, incubation.

Factors associated with milk urea nitrogen on milk yield and milk composition were investigated in this study regarding feeding management and Physiological status of lactating cows. The data for 3 years between 1999 and 2002 for this study were collected from 129,645 cows by Korean Agricultural Cooperatives Federation. The objectives of this study were to describe the relationships between milk urea concentrations and seasonal factors, cow factors and production of milk, milk fat, protein and somatic cell score(SCS). Milk urea was highest in summer and it also showed a nonlinear association with milk yield. Milk yield was higher at milk urea concentrations of 21 ${\sim}$ 24mg/dl, however it decreased at higher level of milk urea concentrations than 24mg/dl. Milk urea was higher with increased parities of cows and in particular, at 3 to 4 parities. There was a negative association between milk urea and SCS in milk. SCS in milk was lowest at milk urea concentrations of 2l${\sim}$24mg/dl. Milk fat and milk protein were greatly affected by days in milk(DIM), year of birth, season and milk urea concentrations, respectively. While milk urea increased in summer, milk fat and protein were decreased. Milk protein decreased according to longer days in milk. With regard to the influences of parity, milk protein in overall was negatively correlated to milk urea in all lactations, however the extent of decrease of milk protein at high concentrations of milk urea was bigger at third lactation. The balanced supply of energy and protein to the animals might have greatly affected the urea concentrations and protein content of milk.

The completion of the rough draft of the human genome is a remarkable achievement. It provides the overall structures of huge DNA molecules that constitute the genome and an outline of the information needed to create a human being. This paper reviewed new ideas, projects, and scientific advances made by the Human Genome Project. We also discussed the future of medicine and biomedical research in postgenomic era.
